The dress is embroidered with national symbols of France.

The ornaments are stylized in the colors of the flag. The blue stripe reflects the sky and represents freedom. The white stripe symbolizes purity and neutrality. The red stripe is associated with the blood shed during the revolution and reflects the desire for equality and fraternity.

Embroidered on the chest is a lily flower, which is a symbol of honesty, devotion, bravery and nobility.

The stylized cockade is considered a symbol of the French Revolution. And the buckwheat flower is used in the ornaments of Ukrainian embroidery and bears a stylized resemblance to the lily flower.
